5 Claims.

My invention relates to improvements in illuminated terrestrial globes. In various commercial types of the illuminated terrestrial globe, the globe proper is generally formed of translucent material, either glass or other desired translucent in such a manner that with the globe in its nor- 1 mal position, it is impracticable to move the globe vertically with respect to its support and with respect to the lamp to permit the globe to be removed for the purpose of renewing the lamp or for the purpose of assembly.

It is one of the objects of my invention to pro vide a support in connection with the meridian or half meridian ring which will permit the globe to be readily removed from its support on the ring without disturbing the lamp connection or without unnecessarily manipulating any of the parts.

1 For the purpose of disclosing my invention, I have illustrated an embodiment thereof in the accompanying drawing, in which: I

Fig. 1 is an elevation of a terrestrial globe embodying my invention; and

Fig. 2 is a detail section showing the manner of supporting the globe and illuminating lamp support.

In the embodiment illustrated, the globe l is preferably of glass, having the map indicia mounted on the exterior thereof. These indicia, may, in practice, be printed on suitable paper segments which are then secured on the outer surface of the glass globe by a suitable adhesive. The globe l at its lower end is provided with a lamp-receiving opening in the walls thereof suiticiently large to accommodate an illuminating lamp bulb, the walls of which opening are preferably protected by a suitable'metal grommet 2 which is adapted to embrace the edges or walls of the opening to protect the same from being base or support may take any desired form. This may be formed integrally with the meridian ring.

This post is provided with an annular shoulder l supporting in turn a washer or bearing member 8 and supported on this bearing member 8 is a supporting disc 9 which is preferably formed of sheet metal and is provided with an annular supporting flange H3. The disc also has an annular raised or struck up portion l i which forms a bearing or bearing surface for the globe. The bearing ii is of just sufficient diameter to take into the opening of the globe so that when the globe is supported on the flange ill, lateral displacement of the globe will be prevented by the bearing II. The axis of this bearing coincides with the polar axis of the globe and at the top of the globe there is provided a pin-receiving opening surrounded by a suitable washer or metal disc 55 having a portion extending into, if desired, an opening in the top of the globe. The upper end of the meridian ring 3 is provided with a hollow boss is through which is threaded a pin ll, the end of which extends through the opening in the top of the globe so that the globe is rotatably supported by the disc 9 and has two bearings, one at the lower end on the bearing l l and one at the upper end on the end of the pin ii.

The post 5 is extended upwardly and immediately above the disc 9 is screw threaded to receive a threaded nut id for clamping the disc 9 between the washer 8 and the nut to thereby maintain the disc in a substantially rigid position. The upper end of this post 5 is inclined at an angle to the axis of the disc 9 and the bearing ii and is screw threaded as at I 9 to receive a lamp-receiving socket 259. This socket is of the usual commercial type provided with a switch adapted to be operated by a pull chain 25 passing downwardly and through an opening 22 in the discs. Likewise the lamp cord 23 passes through an opening into the disc upwardly to the lamp socket. The socket is adapted to receive the usual illuminating lamp fi land it will be noted that in the specific structure illustrated the lamp socket and lamp are supported'in such a manner that the axis of the lamp socket and lamp is vertical and extends at an angle to the axis of the disc and bearing l i Due to the fact that the axis of the lamp and its associated socket extends at an angle to the axis of the globe and due to the fact that the bearingmember H is comparatively short upon the reany way affect the proper illumination of the globe nor does it perceptibly afiect the even distribution of illumination throughout the surface of the globe, nor does this arrangement cause unsatisfactory shadows to be cast on the surface of the globe.

The structure is such that the parts may be all rigidly mounted and maintained in this rigid position even when the globe is being removed therefrom.

I claim:

1. In a terrestrial globe mounting, the combination with a base and a meridian ring sup ported thereby, of a globe support rigidly carried by said base comprising a supporting member and a bearing member extending upwardly from said supporting member, a second support for the globe diametrically opposite said first support and releasable to free the globe therefrom, said bearing and supports having a common axis, a hollow globe rotatably carried by said supports having its rotatable axis common to the axes of said supports and base having an opening for receiving said bearing member and tiltable on said first-mentioned support sufficiently to clear the same or" said meridian ring to permit removal from said support, means for supporting a lamp above said first mentioned support in a position to be projected through said opening into said globe and on an axis extending at less than a right angle to the globe support axis and inclined in the direction the globe is tiltable to permit said globe to be tilted on its base and removed therefrom, the height of said bearing member being such as to permit'the tilting of the globe on the supporting member to clear the globe of the meridian ring.

2. In a terrestrial globe mounting, the combination with a base and a meridian ring supported thereby, a globe support rigidly carried by said base comprising a supporting member and a bearing member extending upwardly from said supporting member, a second support for the globe diametrically opposite to said first support and releasable to free the globe, said supports and bearing member having a common axis coincident with the polar axis of the globe, a hollow globe having an opening therein rotatably supported on said first-mentioned support and adapted to receive in said opening said bearing member and tiltable on said first-mentioned support to clear said meridian ring and permit removal from said support, means for supporting a lamp above said first-mentioned support in a position to project through said opening into said globe and on a vertical axis which inclines away from the polar axis in the direction the globe is tiltable to permit a vertical removal of the globe after the same has been tilted on its support, the height of the bearing member being such as to permit the tilting of the globe on its support to clear the globe of the meridian ring.

3. In a terrestrial globe mounting, the combination with a base and a meridian ring supported thereby, a supporting disc rigidly supported on said base, a releasable pivotal sup port for the globe mounted on said meridian ring at a point diametrically opposite said disc, an annular flange extending upwardly from said disc smaller in diameter than said disc to leave, an annular supporting shoulder on said disc, said disc flange and pivotal supporting member having .a common axis, a hollow terrestrial globe having an opening therein supported on said first-men-I tioned support and adapted to receive said annular flange'and tiltable on said support to clear the meridian ring for the purpose of removal, an

electric lamp support extending upwardly from d said disc and supporting a lamp in a position to be projected through said opening into said globe and on an axis extending at an angle to the axis of said disc and inclined in the direction the globe is tiltable to permit thetglobe to be removed from said disc after it has been tilted, the height of the annular flange being such as to permit the tilting of the globe on the disc v to clear the globe of the meridian ring.

4, In a terrestrial globe mounting, the com I bination with a base and a meridian ring supported thereby, of a globe support rigidly carried by said base comprising a supporting member,

and a bearing member extending upwardly from said supporting member, a second support for theglobe diametrically opposite the first support andreleasable to free the globe therefrom,said bearing and supports having a common axis, a hollow terrestrial globe rotatably supported on said firstmentioned support having an opening therein to receive said bearing and tiltable on said support to clear the same from the meridian ring to permit removal of the globe and means for supporting a lamp above said first-mentioned support and within said globe with the axis of said lamp inclined to the rotatable axis of said globe and supporting members and in the direction the globe is tiltable to permit said globe to be removed from the first-mentioned supporting member when in its tilted position, the height of the bearing member being such as to permit the tilting of the globe on the supporting member meridian ring at a point diametrically opposite,

said disc, the axis of said disc, annular flange, and pivotal supporting member being common,

a hollow terrestrial globe having an opening therein supported on said first-mentioned support and adapted to receive in said opening said flange, the height of the annular flange being such as to'permit the tilting of the globe on the shoulder to clear the globe of the meridian ring, and a lamp socket extending upwardly from said disc into said globe on an axis extending at an angle to the axis of said disc and inclined in the.

direction the globe is tiltable to permit a removal of the globe from its support after having been tilted.
